Testing continuity of a single wire from a distance


I’m replacing the 3-way switches in my house and as it turns out, the color scheme for the wires aren’t what I’d expect (ground, 2 black, 1 white. White was the hot, one black was load and one was traveler). I’m looking for a good way to test continuity as to find the traveler between switches, currently I’m dragging around a long copper wire which is less than convenient. I have a coaxial continuity testing tool that has a remote end which was extremely handy in mapping out which cable was which where it meets the splitter. The only thing I’ve been able to find like that was a remote continuity tester which required 2 wires, but I’m only looking for the one. I can find the hot, I need to be able differentiate between the load and the traveler. Any advice? via /r/DIY https://ift.tt/2KlpNnC
